Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft einen Rührarm fürThe invention relates to a paddle for

Röstöfen, Tellertrockner usw. Es sind nun für solche Zwecke hohle Rührarme bekannt, die mit Ankerschrauben im inneren Rohr an der Königswelle befestigt werden.Roasting ovens, plate dryers, etc. There are now known hollow agitator arms for such purposes, which are attached to the vertical shaft with anchor bolts in the inner tube.

Das Wesen der vorliegenden Erfindung besteht nun darin, daß die Ankerschrauben durch zwei diametral gegenüberliegende Rührärme hindurchreichen, derart, daß das Anpressen des konischen Auflagezapfens des Rührarmes lediglich durch den Druck der Ankerschrauben auf das innere Rohr ohne Beanspruchung des äußeren Endes der Rührarme erfolgt.The essence of the present invention is that the anchor bolts pass through two diametrically opposed agitating arms in such a way that the pressing of the conical support pin of the agitator arm only by the pressure of the Anchor bolts on the inner tube without stressing the outer end of the agitator arms he follows.

Diese Anordnung bietet betriebstechnisch den äußerst wichtigen Vorteil, daß der von heißen Gasen und heißem Material umgebene und demzufolge gegen Biegung und Druck nur wenig widerstandsfähige Rührarm für Zwecke der Befestigung nicht beansprucht wird.From an operational point of view, this arrangement offers the extremely important advantage that the surrounded by hot gases and hot material and consequently against bending and pressure only little resistant agitator arm for the purpose of attachment not claimed will.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown in one embodiment.

Fig. ι ist ein senkrechter Schnitt, und
Fig. 2 ist ein wagerechter Schnitt.Fig. Ι is a vertical section, and
Fig. 2 is a horizontal section.

Der Rührarm α sitzt mit seinem konischen Auflagezapfen b in der entsprechenden Bohrung der Königswelle c. Der konische Auflagezapfen ist ausgebohrt. In dieser Bohrung sitzt ein mit Absatz versehenes Rohr d. Durch eine Ankerschraube e wird der Arm α in die Bohrung der Königswelle c gepreßt. In der Zeichnung ist die Ankerschraube durch zwei gegenüberliegende Rührarme gezogen. Das Kühlmittel strömt aus dem inneren Räume der Königswelle c durch im Rohr d vorgesehene Löcher f in den Rührarm α und aus diesem durch Löcher g in den äußeren Raum der Königswelle c.The agitator arm α sits with its conical support pin b in the corresponding hole in the vertical shaft c. The conical support pin is drilled out. In this hole sits a tube provided with a shoulder d. The arm α is pressed into the bore of the vertical shaft c by an anchor screw e. In the drawing, the anchor screw is pulled through two opposing agitator arms. The coolant flows from the inner space of the upright shaft c through holes f provided in the pipe d into the agitator arm α and from this through holes g into the outer space of the upright shaft c.
